ABSTRACT:
A calling card telephone call may be automatically initiated by the aid of an intelligent cared (10) having the capability of generating a first and second sequences of DTMF signals. Upon actuating the card in a first manner, the card generates the first DTMF signal sequence that corresponds to a calling card carrier access number. Upon actuating the card in a second manner, the card generates the second DTMF signal sequence corresponding to a card holder personal identification code. Thus, by actuating the card in the first and second manner, a card holder can effectuate the input of the carrier access number and card holder personal identification number, respectively, without having to enter this information via a key pad, thereby gaining reducing the incidence of card fraud.
